40 year old running again... any tips to get to a 1/2 marathon?

Hi everyone! I've just started running again and well, I'm definitely not in my 20s anymore. I have a 3-1/2 year old and a one year old and have started pushing them both (55lbs) in a BOB stroller first thing in the morning for almost 4 miles in an hour. Then in the evening I will try to run. Looking for tips on what to eat before and after both workouts. Look forward to chatting!
